Does this hold the keys, and deliver signed transactions upon request, or does it connect to the peer-to-peer network and act as a validator?

It only holds keys, with the idea that the validator is kept offline except for communication with sentries.

There are some other options for Tendermint key storage which claim to act as a "validator", but really all these options do is provide equivalent functionality to TMKMS, but suggest you put your "validator" (i.e. the one which signs validated blocks, and proposes blocks) on the edge of the network. This is largely a terminological difference, but the real idea of the sentry architecture is that the Tendermint node which is validating blocks and asking TMKMS to sign PreVotes/PreCommits/Proposals is only seeing P2P traffic which has first passed through a sentry.

Software like this could potentially allow a single Raspberry Pi to validate multiple networks although I'm not sure if that's desirable from a decentralization / reliability perspective.

The hardware requirements for TMKMS are minimal and this should work if you have a Raspberry Pi running Linux.

Hey thank you, I'm getting deeper and deeper into my validator journey and I think that soon in Raspberry Pi of the type that you've described here will enter it.
